Dunno...I think they're just going to show off their main games. (Smash, Mario, MK, and I think Pikmin 3)

I love Erica (Strike Witches), Yuuki, and for some odd reason, Megumi (School Rumble)
Update: Also love Yukari and Mizore from Rosario + Vampire.
Another Update: Also Amber and Xiao Pai from Rune Factory 4.
More Updates: I HAZ YOUTUBE!!!
